ok,
so just downloaded all apps again and did apt-get upgrade/ update, install nano, wget, bzip2 & unzip. These are the only deb files listed in the archives cache. This time I downloaded 44 apps via app manager, not one of these are listed in the archives folder and hence none copied across. It is mainly the apps manager debs I am trying to grab. I assume these are either erased immediately or downloaded to another folder?
